Doomheim

I was able to destroy the npc's guarding the gate, then when I warped to the next section, I see the next set of npcs, but past them is the main objective: a warehouse sitting on top of a large rock. I rush over to the warehouse, destroy it, and then kill all the npcs. No objective completion check mark. I went back to the station, and tried to hit complete, but it says I haven't completed yet. I tried warping back to that area, but there is nothing there. Bugged?
